Template:Nutshell Equity Derivatives 3.1(f)

3.1(f) “Expiration Date” will be specified in an Option Transaction Confirmation (or, if it is not a Scheduled Trading Day, the following Scheduled Trading Day), unless that day has become a Disrupted Day before the Latest Exercise Time. In this case it will be the next undisrupted Scheduled Trading Day, though if eight Scheduled Trading Days in a row are Disrupted Days, the eighth one, even though a Disrupted Day, will be the Expiration Date. In any case, if an Option Transaction is exercised on a Scheduled Trading Day that would have been an Expiration Date had it not been a Disrupted Day, that day will be treated as the Expiration Date when determining whether an Exercise Date has occurred during the Exercise Period.
